Abstract (en)

[origin: EP0586718A1] The object of the present invention is to reduce the number of cycles of charge-discharge operation required in the formation process involved in manufacturing of a sealed type nickel-hydrogen cell having a large high-rate discharge capacity. According to the present invention, a sealed type nickel-hydrogen cell is subjected to at least one cycle of charge-discharge operation and thereafter kept at a temperature in the range of about 30 DEG C to 60 DEG C for a predetermined length of time.
